I wanted to know if a 360 Tummy tuck, Extended Tummy tuck and a lower body lift are the same things but just different terms?

Many surgeons make a distinction between a "regular" tummy tuck and an "extended" tummy tuck, though I don't typically differentiate between the two.  Either of these procedures address the loose skin of the front of the abdomen.  The more loose skin is present, the longer the scar needs to be to achieve the greatest degree of improvement in shape and avoid a dog ear (bunching of skin at the end of the scar).  It is not worth limiting the scar length by a few centimeters if the trade-off is a less substantial improvement in shape.  A 360 tummy tuck is a more extensive procedure to remove loose skin of the front of the abdomen, love handles (hips), and lower back.  It is also called a "belt abdominoplasty" or a "lower body lift."  It results in a scar that goes all around the torso (low on the abdomen like a regular tummy tuck scar and just above the buttocks on the back).  This procedure can make a more complete improvement in the shape of the torso, but is more extensive, more expensive, has some higher risks, and has a longer recovery.  In my practice, most patients who choose this option are patients who have lost a significant amount of weight and have severe skin laxity.

Your confusion is understandable because there is a universally accepted nomenclature for the various kinds of tummy tucks  (abdominoplasties). 
Abdominal Panniculectomy - remove the overhanging lower abdominal skin
Mini-Abdominoplasty - remove excess lower abdominal skin, +/- love handle liposuction, +/- some degree of rectus muscle plication (incision usually smaller)
Abdominoplasty - usually involves low incision, hip-to-hip, umbilicus (belly button) is frequently moved, rectus abdominis muscle usually plicated, +/- love handle liposuction
Extended Abdominoplasty - would be an abdominoplasty with incisions going further back, but still accessible without flipping you over
Circumferential Abdominoplasty - abdominoplasty + buttock lift; incision goes all the way around one's waist
360 Degree Abdominoplasty = Circumferential Abdominoplasty
Torsoplasty = Circumferential Abdominoplasty
Fleur-de-Lis Abdominoplasty - abdominoplasty that also has a vertical incision running up the midline; adds a prominent scar and usually only done in patients with a history of massive weight loss
Lipoabdominoplasty- combines more liposuction than would be performed with a traditional abdominoplasty with skin removal

This is an excellent question, because as ABMS certified Plastic Surgeons, we have created different terms to describe the different types of surgery we offer patients that desire body contouring. If you have extra skin on your abdomen, we typically recommend you undergo a tummy tuck (abdominoplasty) which typically limits the incision to your lower abdomen and is hidden in a bikini line. If the excess skin extends around your hip bones, but not all the way around your back, we call this procedure an extended tummy tuck. Again our goal is to place the entire incision under your bikini. If you also have excess skin in your buttock area and outer thigh area, we offer you a lower body lift that could also be called a 360 tummy tuck. The key point is to consult with a ABMS certified Plastic Surgeon who can evaluate your anatomy and your goals for body contouring and who then offers you the procedure that will best meet your expectations. Good luck!

Extended TT: It is consider the skin removal using an incision a bit further back the hip bone, perfect for patients who have significant saggy skin on abdomen and bit on sides.CTT: 360 incision for skin removalLBL: Means the combination of the CTT with buttocks lift, outer thigh lift.I combine ALL above with Muscle repair, pubic lift when needed and the majority with liposuction and fat grafting to buttocks/hips when needed Dr. Cardenas

A standard TT incision goes
hip bone to hip bone, sometimes a bit shorter; it involves repair of the rectus muscles and removal of loose, excess tissue around the abdominal areas to improve body contours.If the incision
goes around the sides and/or around the sides and back, because of the incision length, it is called an ETT.  If the incision goes all
the way around (360 degrees) it is then called a body lift or circumferential
tummy tuck. A lower body lift will improve the abdomen, the back, and perhaps the buttocks and outer thighs. Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Different abdomens require different procedures.  Some people have excess fat, but good skin quality.  Usually liposuction alone will help that patient.  Some people have excess fat and just loose skin in the lower abdomen and good muscle tone.  A mini-tummy tuck would be a great option.  This procedure includes liposuction and removal of just some skin from the lower abdomen.  Patients who have loose skin throughout the abdomen and lax muscle would require a full Tummy Tuck.  Patient who have significant weight loss or have had a bariatric procedure, like a lap band or sleeve, who need an extended tummy tuck or even a full body lift to address the extra skin in the back.  I hope this gives you a better understanding of the differences.  Please contact a Board Certified Plastic Surgeon to have a consultation to determine what would be best for you.

There are no definitions set in stone but an extended tummy tuck usually means the incisions go beyond the front of the abdomen (to the sides) while a 360 or circumferential, or body lift, goes all the way around. 

Goal of Lower Body Lift is to do buttock and outer thigh lift. 360 degree tummy tuck and extended tummy tuck imply different degrees of tummy tuck. Extended is less that 360 degree.Thus they are not the same things.

Thank you for your question. 360 TT and lower body lift and circumferential TT are the same. Extended TT is extension of regular TT incision to address more loose skin on either side. 

Extended TT, the incision is only on the abdomen and goes past the hip bones from side to side.360 TT or lower body lift, have some differences, but some PS may use them as the same. Lower body lift is usually more extensive and can lift the superior buttock area and the lateral or outside thigh area to some degree.ask your BCPS what they think the differences are. and let them know, what you are trying to improve on. good luck, Dr. Leake
